Abstract
Description
Technical Field
[0001] The present invention relates to the field of mobile communication technology, and in particular to a method, system, device and storage medium for upgrading RRU software of a pico base station. Background Art
[0002] Pico base stations are small, low-power base stations that access the mobile core network through fixed broadband to provide LTE services to users. They are mainly used in small and medium-sized indoor places such as enterprises, offices, business halls, and Internet cafes to quickly provide LTE capacity and solve the problem of low LTE signal coverage. The Remote Radio Unit (RRU) is the main component of the base station. Its main function is to convert the baseband digital signal into a radio frequency signal and then amplify it and transmit it through the antenna to achieve wireless coverage of the signal.
[0003] At present, there is a risk in the version upgrade method of the Pico base station RRU: after the RRU loads the new version issued by the BBU (Building Baseband Unit), if there is a fault in the new version of the RRU, the BBU and RRU cannot establish a link normally. At this time, the RRU cannot restore the fault through remote control access, and maintenance personnel are required to go to the site to handle it, which will incur huge manpower cost resources. Summary of the invention
[0004] The present invention provides a method, system, device and storage medium for upgrading the RRU software of a pico base station, aiming to ensure that the RRU can be normally connected to the BBU during the software upgrade process, thereby ensuring the normal operation of the signal communication of the pico base station.

[0019] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
[0020] See also Figure 1 In one embodiment, the present invention provides a method for upgrading RRU software of a pico base station, comprising: S101: Create a backup area for the RRU software, where the backup area is used to back up the current software version of the RRU software.
[0021] A main area and a backup area of the RRU software are created on the memory of the RRU. The main area is used to store the RRU software that is updated and used in real time, and the backup area is used to back up the current software version of the RRU software.
[0022] S102: Obtain a version upgrade instruction of the RRU software, and upgrade the main area software version of the RRU software.
[0023] After the RRU is connected to the base station, when the network management initiates a base station version upgrade task, the RRU receives the software version upgrade instruction and upgrades the RRU software version.
[0024] S103: After the upgrade is successful, if the baseband processing unit cannot normally establish a link with the upgraded RRU software version, the current software version of the main area is automatically rolled back to the software version of the backup area.
[0025] See also Figure 2If you want to upgrade the RRU software version from versionX to versionY, first back up the main area software versionX in the backup area, and then upgrade the main area software versionX to versionY. After the upgrade is successful, if the baseband processing unit can establish a link with the software version versionY normally, the backup area software version will be updated to the current software version versionY of the main area. If the baseband processing unit cannot establish a link with the software version versionY normally, the current software versionY of the main area will be automatically rolled back to the backup area software versionX.
[0026] The upgrade method of the pico base station RRU software in this embodiment creates a main area and a backup area of the RRU software, and backs up the software currently running on the RRU. During the version upgrade of the RRU software, if the upgraded version has a fault and cannot establish a normal link with the BBU, the backup software in the backup area can automatically roll back to the previous version to ensure that the RRU can always establish a normal link with the BBU, thereby ensuring the normal operation of the pico base station signal communication.
[0027] See also Figure 3 In one embodiment, a method for upgrading software of a pico base station RRU includes: S201, creating a backup area of the RRU software, where the backup area is used to back up the current software version of the RRU software.
[0028] S202: Obtain a version upgrade instruction for the RRU software.
[0029] S203, the baseband processing unit detects whether the version to be upgraded of the RRU software is consistent with the current version.
[0030] S204, if they are inconsistent, the baseband processing unit sends the version to be upgraded to the RRU. If they are consistent, no upgrade is required.
[0031] For details, see Figure 4 , if the software version of a newly-delivered RRU is upgraded, the software version of the RRU main area is the baseline version, and a backup area of the RRU software is created, and the backup area is used to back up the baseline version of the RRU software; Obtain a version upgrade instruction of the RRU software, and upgrade the baseline version of the RRU software main area to version 1; After the upgrade is successful, if the baseband processing unit can establish a link with the upgraded RRU software version normally, the backup area software version is automatically updated to the current software version version1 of the main area; If the baseband processing unit cannot normally establish a link with the upgraded RRU software version, the current software version of the main area is automatically rolled back to the baseline version of the backup area.
[0032] S205, upgrade successful.
[0033] S206, determining whether the baseband processing unit can normally establish a link with the upgraded RRU software version.
[0034] Specifically, after the upgrade is successful, the RRU automatically detects whether the upgraded RRU software version can normally establish a link with the baseband processing unit.
[0035] S207: If yes, automatically update the software version of the backup area to the current software version of the main area.
[0036] Specifically, if the baseband processing unit can establish a link with the upgraded RRU software version normally for a second preset time period, such as 40 minutes, but not limited to 40 minutes, the backup area software version is automatically updated to the current software version of the main area.
[0037] S208: If not, automatically roll back the software version of the primary area to the software version of the backup area.
[0038] Specifically, if the baseband processing unit still cannot establish a link with the upgraded RRU software version after a first preset time, such as 10 minutes, but not limited to 10 minutes, the current software version of the main area is automatically rolled back to the software version of the backup area. The method for upgrading the RRU software of the pico base station of the present embodiment creates a main area and a backup area of the RRU software in the memory of the RRU, and backs up the software version of the RRU main area that is currently operating normally. During the process of upgrading the software version of the RRU, if the upgraded software version cannot establish a link with the BBU, the RRU automatically detects this situation and rolls back the software version of the main area to the software version of the backup area; if the upgraded software version can establish a link with the BBU, the software version of the backup area is updated to ensure the connection between the RRU and the BBU during the software update process, thereby ensuring the normal operation of the pico base station, avoiding the situation where maintenance personnel need to go to the site to handle the RRU software upgrade failure, reducing human resource costs, and improving work efficiency.
